I can't say 100% sure, but I think it's no problem. it's free advertisement I'm almost sure, gregg and peter wouldn't care if you have it on your site (as long it's in a positive way, not with some freaky stuff )

Do you think I can use pictures from ansarixprize.com on my site? It would be nice to have a picture of SpaceShipOne on the first page. Do you know someone that I can contact and ask if I can use pictures and other information from ansarixprize.com? I prefer if I didn't have to ask if I can use pictures all the time. This is my first webpage so I don't know the regulations.
